The present invention relates to a device generating a hot air flow, including an air source generating an air flow at its outlet (17), a heating system (13) generating heat energy and heat-exchange elements (27) capable of storing heat energy generated by said heating system (13) and of yielding this heat energy to said air flow. According to the invention, said heating system (13) and said air source are mounted fixed, and said heat-exchange elements (27) are arranged on a mobile support (3) capable of continuously renewing the heat-exchange elements (27) arranged in said air flow and previously heated by said heating system (13).

Device for generating a hot air flow

The combustion chamber of the ramjet is mounted on a support which allows partial freedom of longitudinal movement. A nozzle is arranged at the intake of the combustion chamber, with a flexible, fluid-filled bladder being disposed between the nozzle and the combustion chamber. Air is blown into the combustion chamber through the nozzle, and fuel is fed into the combustion chamber to achieve combustion. The pressure of the fluid in the bladder is measured.
